Description
The ATLAS Collaboration has performed precision measurements
of the transverse momentum of the Z/gamma* boson and the angular
correlations of the Drell–Yan lepton pairs with the phi* observable,
in different di-lepton invariant mass and rapidity regions. These
measurements are sensitive to soft resummation effects and hard jet
emissions for small and large momentum transfers, respectively,
probing QCD in a unique way. Production of jets in association with a
vector boson is an important process to study QCD in a multi-scale
environment. The cross section, differential in several kinematics
variables, have been measured with the ATLAS detector in 7 TeV
proton-proton collisions up to high jet multiplicities and compared to
state-of-the-art QCD calculations and Monte Carlo simulations.
